Optimization Based PAPR Reduction Approach with PTS-TR Block Modeling

OFDM is orthogonal frequency division multiplexing technique is studied by the researchers. This technique has an issue of PAPR(Peak-to-Average Power Ratio) which must have low value for better communication. Various mechanisms have been proposed to reduce PAPR. However, there are very complex and has low accuracy. In this paper, the existing approaches for reducing PAPR value are studied and a novel PAPR reduction technique is proposed by applying the optimization algorithm along with PTS-TR (Partial Transmit Sequence-Tone Reservation). Grey Wolf optimization is implemented to achieve reduced PAPR. The system is evaluated and simulation results are carried out using MATLAB. The results show that the traditional approach is surpassed by a novel technique.
